Etymology

Origin of founder1

First recorded in 1275–1325; Middle English found(o)ur, foundere, fundre “original builder of a city, church, castle, or city; founder of a country,” from Anglo-French fundur, from Old French fondeor, from Latin fundātōr-, stem of fundātor; see origin at found 1; see also -er 1 ( def. )

Origin of founder2

First recorded in 1300–50; Middle English foundren, funder, fonder, from Old French fondrer “to plunge to the bottom, submerge,” from Vulgar Latin fundorāre (unattested), derivative of fundor-, an s -stem noun interpreted as stem of Latin fundus, actually an o -stem noun (stem fund- ) “bottom”

Origin of founder3

First recorded in 1400–50; Middle English foundour, founder, from Old French fondeur, from fondre “to melt, cast”; see origin at found 3, -er 1

Explanation

The person who creates an organization or a company is known as the founder. Founder is also a verb meaning "fail miserably," which is something a company's founder hopes the company will never do. As a noun, founder means "the beginner or originator of something." You might talk about the founder of a nation, the founder of club, or the founder of a website. As a verb, founder can mean “stumble,” like when you trip and fall, but more generally it means "collapse or fall apart." A sports team might founder by slumping on a ten-game losing streak; a ship that sinks in a bad storm can be said to have foundered at sea.
